ABSTRACT
In the title compound, C(15)H(9)Cl(2)F(3)N(2)O(2), the 1,6-dihydro-pyrano[2,3-c]pyrazole ring system is almost planar, with a maximum deviation of 0.0226 (14) Å, and forms a dihedral angle of 69.90 (6)° with the benzene ring. In the crystal, mol-ecules are linked into a helical chain along the c axis by C-H⋯O hydrogen bonds.
